DOOR-OPENING DEVICE.

Application filed August 24, 1916.

To all whom it may concern:

Be it known that I, VILLIABI R. Router, a citizen of the United States,residing at Iota, in the county of Allen and State of Kansas, haveinvented a new and useful Door-Opening Device, of which the following isa specification.

The object of the invention is to provide a simple and comparativelyinexpensive door opening device particularly adapted for use inconnection with screen doors whereby the same may be opened by footpower when, as with waiters in hotels, etc., the hands are otherwiseoccupied.

Further objects of the invention will appear as the descriptionproceeds, it being understood that changes in the precise embodiment ofthe invention herein disclosed, can be made within the scope of what isclaimed, without departing from the spirit of the invention.

In the drawings,

Figure 1 is an elevation of a device embodying the present inventionapplied in 01)- erative position to a door.

Fig. 2 is a plan view of the same showing the positions of the parts indotted lines when the door is partly open.

Fig. 3 is a detail view of the foot bracket or guide.

The device consists essentially of a lever 10 having a short arm 11extending at an obtuse angle from its long arm and with which isconnected an operating element, in this instance consisting of a footlever or pedal 12, said lever 10 being fulcrumed as at 13in a suitablesupporting bracket 14 on the door casing, and the long arm thereof beingfitted slidably in an upwardly projecting guide 15 secured to the door.A spring 16 is interposed between the guide 15 and a fixed shoulder 17on the lever, the parts being so positioned that as the door swingstoward its open position the distance between the guide 15 and thefulcrum of the lever will be shortened to thereby compress the spring16, whereupon, when the door is released the ex pansion of the springwill eifect the closing thereof.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Serial No. 116,659.

The connections between the operating lever and the foot pedal mayconsist of the wires or rods 18 and 19 and the interposed bell, cranklever 20. The upper rod 18 extends behind the guide 15 and lever 10 andis connected to the lever arm 11.

The foot pedal is preferably fulcrumed as. at 21 in a bracket 22 havingparallel sides between which the pedal is free to swing.

Preferably the bracket upon which the operating lever is mountedconsists of a base plate 22 from which project parallel cars 23, spacersor washers 24; being intcrposer between said ears and the lever throughwhich the pivot pin or bolt 13 projects.

Moreover it should be noted that if the door is opened far enough tocarry the guide 15 beyond a plane perpendicular to the normal plane ofthe door and passing through the pivot 13, the tendency of the spring 16will be to hold the door open, while permitting it to be closed simplyby swinging it toward its closed position beyond the said perpendicularplane in the oppositeor closing direction.

What is claimed is A door operating device embodying a bracketattachable to a door casing, a lever fulcrumed to said bracket andhaving a long arm and a short arm extending at an obtuse angletherefrom, anupwardly projecting guide attachable to a door, said longarm being slidable through the guide, said long arm having a shoulder, aspring upon said long arm between said shoulder and guide for closingthe door, and operating means including a rod extending behind saidguide and lever and connected to the short arm of the lever.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
